I think you should read everything you can. In my case, by the age of 10, I'd read every book in the Omaha public library about investing, some twice.
You need to fill your mind with various competing thoughts and decide which make sense.
...I will give you two pieces of advice. Invest as much in yourself as you can; you are your own best asset by far. Then follow your passion; you want to be really excited to get out of bed every morning.
The most common cause of low prices is pessimism - some times pervasive, some times specific to a company or industry. We want to do business in such an environment, not because we like pessimism but because we like the prices it produces. It's optimism that is the enemy of the rational buyer.
If you invested in a very low cost index fund - where you don't put the money in at one time, but average in over 10 years -you'll do better than 90% of people who start investing at the same time.
I always say that in investing you want to buy stock in a company that has a business that's so good that an idiot can run it, because sooner or later one will. We have a country like that.
I bought my first stock in 1942, in the summer of '42. I was 11 years old. And so 75 years have gone by. And I have never known what the market's going to do the next day. And that's not my game. My game is to decide whether I'm in the right economy, which America's definitely been ever since that time. The Dow has gone from 100 to 21,000 during that time. And no matter what the headlines say, or terrible things are happening - we were losing the war in the Pacific when I first bought stocks.
I think once you start putting phony figures into financial statements, you get in a lot of trouble. And we've seen so much of that in the last 20 years.
If you do smart things and use leverage and do one wrong thing along the way, it could wipe you out, because anything times zero is zero. But it's reinforcing when the people around you are doing it successfully, you're doing it successfully, and it's a lot like Cinderella at the ball.
Our investments continue to be few in number and simple in concept: The truly big investment idea can usually be explained in a short paragraph. We like a business with enduring competitive advantages that is run by able and owner-oriented people. When these attributes exist, and when we can make purchases at sensible prices, it is hard to go wrong (a challenge we periodically manage to overcome).
In the end, alchemy, whether it is metallurgical or financial, fails. A base business can not be transformed into a golden business by tricks of accounting or capital structure. The man claiming to be a financial alchemist may become rich. But gullible investors rather than business achievements will usually be the source of his wealth.
Take the probability of loss times the amount of possible loss from the probability of gain times the amount of possible gain. That is what we're trying to do. It's imperfect, but that's what it's all about.
